Clarke revealed that he's had a project in the works for a while now called ANTI HERO. He's even created an ANTI HERO symbol, or sign, that has appeared in several other productions, like Clarke's film 4,3,2,1 and the Channel 4 series Top Boy, since he first came up with the idea.

Here's exactly what Clarke had to say about ANTI HERO:

"It’s a british vigilante Superhero film (That Still Might Happen) and I had leaked the sign in a few different places in 4321, including on that bin, because i was planning on doing that next. We were with a good company that waited until they approved the script and we were ready to shoot then said “it might not be a (the company name) Film” possibly because it was “Too Urban” who knows. So I went and did others things, but the script is still ready to go and i’ve put new directors on it now."
